Jennifer Lopez says her 2012 divorce from singer Marc Anthony was "a tremendous low" in her life. Nonetheless, she says in the new issue of People magazine, "I wouldn't change anything [about my past] because it made me who I am" and that the breakup has allowed her to "take a look at what was going on" in terms of relationships. "As women we can sometimes give ourselves away," Lopez, 44, says. "I was certainly guilty of that for some time. Now I realize I am good on my own, so now I can share my life with somebody." For the past two years, the mother of two has been in a relationship with former backup dancer Casper Smart.
